Maybe this question belongs in the Grammar forum. I'm a novice both in the Russian language and on these forums. So, please bear with me. Anyhoo, I'm wondering if someone could give me some pointers on how to decline proper names. For example, "Konstantin" is in the nominative case. What does it look like in other cases? If I choose to call this person "Kostya," the whole declension table, I guess, will change too. Ugh... Will I ever get this language? Is it a general rule that you add the "a" to names that end with a consonant (Pavel, Oleg, Vladimir, etc.) in the accusative case? Is there a web page where I can go learn more about this? Thank you very much in advance.
